摘要
为克服稳态仿真不能模拟系统动态行为、所给信息不够全面的缺点 ,对电力系统的并列与解列操作进行了动态仿真 ,并给出并列开关两侧频率差、电压差与稳定裕度的关系曲线 。
Static state simulation in DTS can not realistically simulate the paralleling/splitting operations. Therefore, thispaper presents a dynamic simulation model to simulate paralleling/spiitting operations. Based on a step by step (SBS)simulation, a curve describing the relationship between dynamic stability margin and frequency difference (af) and voltagedifference (aV) can be obtained. By using this curve. the setting values of automatic synchronizing devices can be selected.The simulation result for a practical case illustrates the viability of the curve.This project is supported by National Key Basic Research Special Fund of China (No. G1998020313).
